Research interests

My research interests lie primarily in contributing to a deeper understanding of the intersection between health and the social determinants of health, particularly as it relates to pathways to and access to healthcare. Access to healthcare for many individuals, particularly those in resource-limited settings or marginalized groups, has historically been plagued by disparities due to sociodemographic characteristics of individuals, and is one of the major challenges facing health systems in developing countries. Barriers and facilitators to accessing public and private healthcare has been the primary focus of most of my research endeavours to date. HIV and Tuberculosis healthcare access research bring together many aspects of global public health issues including the relationship between health outcomes and the social determinants of health, impacts of political trends and government will, global health priorities and roles of donor agencies. With the COVID-19 pandemic, there is evidence that disparities in healthcare access are widening. I am also interested in researching best practices for healthcare delivery recovery from the impacts of the COVID-19 pandemic.
